Communists and Socialists believe that the good of the 'whole' is more importnat than the good of the few.
that is a belief in human sacrifice.
It is well known that they send their true believers off to die while the children of the powerful are 'in the band' and not put into harms way.
It is well known that aggitate and do poison mentoring and cause problems and breed disfunction.
It is well known that they set up a hunger games situation and let people fight amoung themselves, and provide no sane council to stop the violence, but blame it instead on political rivals.
They sacrifice the young of the 'lower classes' in endless wars againt their relatives who run the other nations.
projection? stupidity? or insight that you don't have, still believing tht the people who brainwashed you to believe the socialist nonsense are your friends?
They litterally will eat you if they get too hungry.
And PS: they are not realy atheists, they worship the opposite and they worship their own power.
